Coronary Flow Reserve and Myocardial Resistance Reserve Changes After Transcatheter Aortic Valve Implantation in Aortic Stenosis

Aortic valve stenosis (AS) induces an alteration in haemodynamic conditions that are responsible for coronary flow reserve (CFR) reduction and coronary microvasculature impairment. Consequently, despite presenting angiographically normal coronary arteries angina and ischemia may occur in some AS patients. 1-7 The effect of transcatheter aortic valve implantation (TAVI) on coronary haemodynamic in AS patients has not been completely clarified yet. Intracoronary continuous thermodilution is an operator-independent, adenosine-free and highly reproducible method, based on the principle of thermodilution.
